What is the Armoloy process?
The Armoloy process is a low temperature, polymorphic, electrophoretic coating based on improved chromium electroplating process technology for chromium alloys. However, unlike the usual chrome plating solutions, the Armoloy process uses a proprietary chemical solution. Solutions and application processes are carefully monitored at all Armoloy facilities. The result is a satin chrome layer that is very hard, thin, dense and of very good bonding quality. Armoloy deposits 99% chrome on the base metal surface of the electroplating process, while conventional chrome will deposit 82 to 88% chrome in most applications.
The process includes cleaning and removal of the metal surface matrix based on the porosity of the base metal surface using a modified electrophoretic coating process using special Armoloy's proprietary means of allowing the chromium metal elements in solution to penetrate into the base metal's surface porosity. It is during this process that the very adhesive properties and qualities of Armoloy are produced. This is actually part of the Armoloy coated metal itself, and the result is a long-lasting bond and a continuous, smooth, hard surface. The surface will not chip, flake, crack, peel or separate from the base metal when exposed to extreme heat or cold, or when subjected to standard ASTM bend tests.
Three basic factors always exist after applying Armoloy metal surfaces:
• Increased wear (70 to 72 C surface hardness)
• Added lubricating properties (including the ability to use Armoloy against Armoloy)
excellent corrosion resistance
application
1. Conventional application
All ferrous and non-ferrous materials are suitable for Armoloy applications. The service life of parts has been increased to 10 times the normal life, even higher in some applications. Aluminum, magnesium, and titanium-based metals, however, are not satisfactory candidates for the Armoloy process.
Because it is a thin, dense coating, Armoloy exhibits very good wear and lubricity properties against surface hardening. Effective when the base metal is 40°C or harder. In severely abrasive applications, the base metal should be hardened to 58 to 62 RC prior to Armoloy application range. Will improve the properties of any metal based on Armoloy, but it is not a substitute for heat treatment.
Table 1 lists the corresponding uses of Armoloy in different hardness ranges .
2. Special application
Armoloy is applied for multiple purposes in different industries. With both Armoloy, metal and plastic molds have better release characteristics and reduced wear (especially when abrasives are involved); cutting tools experience longer wear life; nuclear components have better antigalling and corrosion resistance; used Die stamping, drawing, forming, blanking have been drastically reduced and working life increased; engine and transmission components (such as valves, valve guides, pistons, gears, splines) have no changes or adverse protection from changes; standard pumps and meters Handles corrosive fluids and materials better; bearings and bearing surfaces run longer, cooler and have better corrosion protection than 440C stainless steel In fact, Armoloy makes it possible to use standard iron steel in place of stainless steel In many applications, Applications include food processing, medical environments, and ball or roller bearings.
Other applications include transmissions, power transmissions, gears, dies, screws, sockets, threaded parts and valves. In the automotive industry, applications include not only engine parts, but also large metal forming dies for automotive body parts.
